I suspect it might be opening the console under the local system account on the remote machine.
You will not see the browser that way.
Can you check with Get-Process if the browser is running ?
You could try to run the remote PowerCLI cmdlets under a different account by using
$rSession = New-PSSession -Credential $credential
Invoke-Command -Session $rSession ...
but I'm not sure if that will actually show the console in the browser in the session.
